On the System of Nonlinear Rational Difference Equations
Abstract:

This paper is concerned with the global asymptotic behavior of positive solution for a system of two nonlinear rational difference equations. Moreover, some numerical examples are given to illustrate results obtained.

Keywords:
Difference equations, stability, unstable, global asymptotic behavior.

APPLE: Providing Absolute and Proportional Throughput Guarantees in Wireless LANs
Abstract:
This paper proposes an APPLE scheme that aims at providing absolute and proportional throughput guarantees, and maximizing system throughput simultaneously for wireless LANs with homogeneous and heterogenous traffic. We formulate our objectives as an optimization problem, present its exact and approximate solutions, and prove the existence and uniqueness of the approximate solution. Simulations validate that APPLE scheme is accurate, and the approximate solution can well achieve the desired objectives already.
Keywords:
IEEE 802.11e, throughput guarantee, priority.
